Description

Technical Field

[0001] This utility model relates to the technical field of demolding devices, specifically a demolding device for an elliptical blade ring mold. Background Technology

[0002] Ceramic oval blade rings have extremely high hardness, good corrosion resistance and wear resistance, and good chemical stability, making them resistant to chemical reactions with other substances. However, ceramic materials are relatively brittle and have poor toughness. They are often used in pad printing machines and other equipment as doctor blade rings, which can precisely control the scraping and transfer of ink to ensure printing quality. The production of oval blade rings usually adopts a mold forming process, and demolding is one of the key steps in the mold forming process.

[0003] A search revealed Chinese Patent Publication No. CN217223338U, published on August 19, 2022, which discloses a demolding device for precision molds. The paper states that "the moving seat 121 will drive the trapezoidal drive platform 122 to move simultaneously, and the trapezoidal drive platform 122 will push the demolding rod body 111 upward through the adjustable screw 114, thereby completing the demolding process." The demolding rod rigidly ejects the product inside the mold, which will cause the product to be subjected to greater pressure locally, and is prone to defects such as cracks, dents or damage at the ejection point. In view of this, in-depth research was conducted to address the above problems, which led to this case. Utility Model Content

[0004] The purpose of this invention is to provide a demolding device for an elliptical blade ring mold, in order to solve the problem mentioned in the background art that rigid ejection can cause excessive local stress on the product, leading to breakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a demolding device for an elliptical blade ring mold, comprising a base plate, a cylinder installed at the middle position of the bottom end of the base plate, a pneumatic telescopic rod installed at the top end of the cylinder, an ejector plate installed at the top end of the pneumatic telescopic rod, and a fixed spring and a slip ring for controlling the flexible ejection of the ejector rod.

[0006] Multiple sliding rods are installed on the outer side of the bottom end of the ejector plate, and a sliding ring that can slide up and down is sleeved on the outer wall of the sliding rod. A limit plate is installed at the bottom end of the sliding rod, and a fixing spring is sleeved on the outer wall of the sliding rod below the sliding ring. An annular plate that can move up and down with the sliding ring is installed horizontally between the sliding rings, and multiple ejector rods are installed at the top of the annular plate.

[0007] Positioning rods are installed on the outer side of the top of the base plate, and fixing grooves are installed at the top of the positioning rods. Lead screws are threaded to both sides and the front and rear ends of the fixing grooves, and knobs are installed at the ends of the lead screws that are far apart from each other. An elliptical blade ring lower mold is provided above the fixing groove, which can be inserted into the fixing groove. Fixing holes for accommodating lead screws are opened inside both sides and the front and rear ends of the elliptical blade ring lower mold. Ejection holes for accommodating ejector rods are opened inside both the fixing groove and the bottom end of the elliptical blade ring lower mold.

[0008] Preferably, the top end of the pneumatic telescopic rod passes through the base plate, and the top end of the pneumatic telescopic rod extends above the base plate.

[0009] Preferably, the ejector plates are all sleeved on the outer wall of the positioning rod, and the ejector plates can slide up and down along the outer wall of the positioning rod.

[0010] Preferably, the fixed springs are all fixedly installed between the slip ring and the limiting plate, and the annular plates form a sliding structure through the slip ring and the sliding rod.

[0011] Preferably, the top ends of the ejector rods all pass through the ejector plate, and the top ends of the ejector rods all extend between the fixing groove and the ejector plate.

[0012] Preferably, the position of the ejector rod matches that of the ejector hole, and the ejector rod can be inserted into the interior of the ejector hole.

[0013] Preferably, the lead screw is positioned to match the fixed socket, and the lead screw can be inserted into the fixed socket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the ejector plate drives the annular plate to move upward, so that the ejector rod passes through the ejector hole and inserts into the interior of the lower mold of the elliptical blade ring until it contacts the product inside the lower mold of the elliptical blade ring. The slip ring generates downward pressure on the fixing spring. Under the reaction force of the fixing spring, the ejector rod slowly ejects the product inside the lower mold of the elliptical blade ring. This structure, through the action of the fixing spring and the slip ring, allows the ejector rod to slowly apply force to the product inside the lower mold of the elliptical blade ring, flexibly ejecting the product and preventing excessive local stress on the product, which could lead to deformation and cracking.
